用Java中的1..N坐标表示玩家

Question

my question is how would you do it to make a code as,

i need a list with players[unique] and for every player i got these coords [x, z]

but for every player there can be more than 1 coordinates[x,z]

i need to save it easly and i have to check the coords of the players every time they trigger an event...

so i have no idea where to start

my english aint good so i gonne try to draw it a little for you hehe

Answer 1

For every player, store the coordinates list in an ArrayList (where Point is a structure that holds the (x,y) coordinates--perhaps java.awt.Point). Make Point implement Serializable . (java.awt.Point already implements Serializable.) Also make the player class implement Serializable. Then it is easy to serialize and deserialize each player (or an ArrayList of them) using ObjectOutputStream / ObjectInputStream .

Answer 2

this one is resolved

made 2 classes Coordinate and Player and made in player an arraylist of coordinate

in the main class i make an arraylist of player...

Saving happens with xml

thx anyway for the help !
